Description

Technical Field

[0001] This application relates to the technical field of building ventilation and dust removal, and more specifically, to a building energy-saving ventilation and dust removal device. Background Art

[0002] During the process of building construction, a large amount of dust will be generated. In order to prevent workers from inhaling a large amount of dust and affecting their physical health, dust removal equipment is often used at the construction site to remove the dust at the construction site. When the existing dust removal equipment is used for a long time, a large amount of dust will adhere to the metal protective mesh plate, and the metal protective mesh plate is not easy to disassemble, so the dust on the metal protective mesh plate cannot be cleaned in time, which will affect the dust removal effect of the dust removal equipment. The prior art CN217519998U discloses a building energy-saving ventilation and dust removal device, including a ventilator and a box body, and uses a protective plate to conduct a preliminary filtration on the dust in the air. The dust removal device provided by the present invention can automatically clean the dust on the protective plate, thus avoiding the influence on the dust removal effect of the dust removal equipment caused by the failure to clean the dust on the protective plate in time. During the long-term use of the protective plate, even if a brush is often used to clean the protective plate, the dust filtered out will still accumulate on the protective plate. Therefore, the protective plate needs to be replaced. However, the above-mentioned protective plate cannot be disassembled, resulting in the inability to disassemble the protective plate to replace a new one when a large amount of filtered dust accumulates on the protective plate.

[0003] The prior art document with the publication number CN 220669674 U provides a building energy-saving ventilation and dust removal device. By disassembling the protective plate, the protective plate can be disassembled and replaced with a new one when a large amount of filtered dust accumulates on the protective plate, thus avoiding the influence on the dust removal effect of the dust removal equipment caused by the failure to clean the dust on the protective plate in time.

[0004] Although the above prior art solutions can achieve the relevant beneficial effects through the structures of the prior art, there are still the following defects: The device simply uses the cleaning method of a cleaning brush, resulting in a poor cleaning effect during the cleaning process.

[0005] In view of this, we propose a building energy-saving ventilation and dust removal device. Utility Model Content

[0006] 1. Technical Problems to be Solved

[0007] The purpose of this application is to provide a building energy-saving ventilation and dust removal device, which solves the technical problems in the above background art and realizes the improvement of the cleaning effect of the filtering component.

[0008] 2. Technical Solutions

[0009] The technical solution of this application provides a building energy-saving ventilation and dust removal device, including a box body, and further includes a filtering component fixed inside the box body and a cleaning component fixed on the box body. The filtering component includes a filter mesh plate and a filter element. The cleaning component includes two liftable brush plates. The two brush plates are attached to the same side of the filter mesh plate and the filter element, and are both placed on the air inlet side of the box body. The cleaning component further includes a plurality of rotatable impact balls, and the impact balls are placed between the filter mesh plate and the filter element. The bottom of the box body is connected through a through hole to a collection component for collecting dust.

[0010] By adopting the above technical solution, wiping and cleaning are carried out by two lifting brush plates, and at the same time, the filter mesh plate and the filter element are impacted by the rotating impact balls. Therefore, under the action of inertia, the sundries on the filter mesh plate and the filter element can be shaken off, improving the dust cleaning effect of the filter mesh plate and the filter element, and making the cleaned dust fall into the collection component for centralized collection.

[0011] As an alternative solution of the technical solution of this application document, a waste discharge port is opened at the bottom of the box body. The collection component includes a collection box and a drawer fixed below the waste discharge port. A drawer opening is provided laterally on the collection box, and the drawer is installed in the drawer opening.

[0012] As an alternative solution of the technical solution of this application document, a strip-shaped hole corresponding to the waste discharge port is opened on the side wall of the box body, and a shielding plate is inserted in the strip-shaped hole, and the shielding plate can shield the waste discharge port.

[0013] By adopting the above technical solution, when the box body filters particulate matter, the shielding plate is inserted into the strip-shaped hole. At this time, the shielding plate shields the waste discharge port, making the lower edges of the filter mesh plate and the filter element in a sealed state. And when it is necessary to clean the dust, the shielding plate is taken out from the strip-shaped hole. At this time, the filter mesh plate and the filter element are placed above the waste discharge port. Therefore, the dust particles after being cleaned by the brush plate fall into the drawer through the waste discharge port under the action of gravity. Finally, the drawer is taken out from the drawer opening, and the dust particles can be centrally cleaned.

[0014] As an alternative solution of the technical solution of this application document, the cleaning component further includes a double-shaft servo motor, a lead screw, a nut, a lower shaft rod and a spring. Guide rods penetrating the box body are symmetrically fixed on the brush plates. A connecting plate is fixedly installed on the four guide rods. The nut is threadedly connected to the lead screw, and the nut is fixed on the connecting plate. The upper shaft rod of the double-shaft servo motor is coaxially fixed to the lead screw. Springs are symmetrically fixed on the lower shaft rod, and the impact balls are fixed on the springs.

[0015] By adopting the above technical solution, the dual-axis servo motor is fixed on the box body. After the dual-axis servo motor is powered on, when the lead screw is driven to rotate counterclockwise, under the action of the thread, the nut drives the connecting plate and the guide rod to move downward. When the lead screw rotates clockwise, it drives the connecting plate to move upward. Finally, the two brush plates are lifted and lowered on the left surfaces of the filter mesh plate and the filter element, thereby realizing the wiping and cleaning of the filter mesh plate and the filter element. At the same time, the lower shaft rod rotates accordingly, and under the action of centrifugal force, the spring is stretched, and the impact ball impacts on the right side of the filter mesh plate and the left side of the filter element. During the impact process, the filter mesh plate and the filter element shake off the dust on the surface.

[0016] As an alternative solution to the technical solution of the present application document, the impact ball is made of solid metal material, and the outer surface of the impact ball is wrapped with a rubber layer.

[0017] By adopting the above technical solution, the impact ball made of solid metal material is used to improve the impact effect, and the rubber layer wrapped on the surface of the impact ball can reduce the wear on the filter mesh plate and the filter element.

[0018] 3. Beneficial effects

[0020] 1. In the present application, the two lifting brush plates are used for wiping and cleaning, and at the same time, the rotating impact ball impacts the filter mesh plate and the filter element. Therefore, under the action of inertia, the sundries on the filter mesh plate and the filter element are shaken off, the dust cleaning effect of the filter mesh plate and the filter element is improved, and the cleaned dust falls into the collection component for centralized collection.

[0028] The present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0029] A building energy-saving ventilation and dust removal device includes a box body 1, and further includes a filter assembly 2 fixed inside the box body 1 and a cleaning assembly 3 fixed on the box body 1. The filter assembly 2 includes a filter screen plate 21 and a filter element 22. The cleaning assembly 3 includes two liftable brush plates 32. The two brush plates 32 are attached to the same side of the filter screen plate 21 and the filter element 22, and are both located on the air inlet side of the box body 1. The cleaning assembly 3 further includes a plurality of rotatable impact balls 37. The impact balls 37 are located between the filter screen plate 21 and the filter element 22. The bottom of the box body 1 is connected through to a collection assembly 4 for accumulating dust.

[0030] Referring to Figures 1-6 , one side of the box body 1 close to the filter screen plate 21 is the air inlet (that is, Figure 2 the left end), and the other end is the air outlet. The filter screen plate 21 intercepts large-particle impurities and dust, and the filter element 22 intercepts small-particle dust. When it is necessary to clean the left surface of the filter screen plate 21 and the filter element 22, at this time, the two lifted brush plates 32 are used for wiping and cleaning, and at the same time, the rotating impact balls 37 impact the filter screen plate 21 and the filter element 22. Therefore, under the action of inertia, the impurities on the filter screen plate 21 and the filter element 22 are shaken off, improving the dust cleaning effect of the filter screen plate 21 and the filter element 22, and making the cleaned dust fall into the collection assembly 4 for centralized collection.

[0031] An impurity discharge port 11 is opened at the bottom of the box body 1. The collection assembly 4 includes a collection box 41 fixed below the impurity discharge port 11 and a drawer 42. The collection box 41 is laterally provided with a drawer opening 411, and the drawer 42 is installed in the drawer opening 411.

[0032] A strip-shaped hole 12 corresponding to the impurity discharge port 11 is opened on the side wall of the box body 1, and a baffle 13 is inserted in the strip-shaped hole 12. The baffle 13 can block the impurity discharge port 11.

[0033] Referring to Figure 2 and Figure 4 When the box body 1 filters particulate matter, the baffle plate 13 is inserted into the strip-shaped hole 12. At this time, the baffle plate 13 blocks the impurity discharge port 11, so that the lower edges of the filter screen plate 21 and the filter element 22 are in a sealed state. When it is necessary to clean the dust, the baffle plate 13 is taken out of the strip-shaped hole 12. At this time, the filter screen plate 21 and the filter element 22 are placed above the impurity discharge port 11. Therefore, the dust particles after being cleaned by the brush plate 32 fall into the drawer 42 through the impurity discharge port 11 under the action of gravity. Finally, the drawer 42 is taken out of the drawer opening 411, and the dust particles can be centrally cleaned.

[0034] The cleaning assembly 3 further includes a double-shaft servo motor 31, a lead screw 33, a nut 34, a lower shaft rod 35 and a spring 36. Guide rods 321 penetrating the box body 1 are symmetrically fixed to the brush plate 32. A connecting plate 322 is fixedly installed on the four guide rods 321. The nut 34 is threadedly connected to the lead screw 33, and the nut 34 is fixed to the connecting plate 322. The upper shaft rod of the double-shaft servo motor 31 is coaxially fixed to the lead screw 33. Springs 36 are symmetrically fixed to the lower shaft rod 35, and impact balls 37 are fixed to the springs 36.

[0035] Referring to Figure 2 and Figure 3 The double-shaft servo motor 31 is fixed to the box body 1. After the double-shaft servo motor 31 is powered on, when driving the lead screw 33 to rotate counterclockwise, under the action of the thread, the nut 34 drives the connecting plate 322 and the guide rods 321 to move downward. When the lead screw 33 rotates clockwise, it drives the connecting plate 322 to move upward. Finally, the two brush plates 32 are lifted and lowered on the left side surfaces of the filter screen plate 21 and the filter element 22, so as to realize the wiping and cleaning of the filter screen plate 21 and the filter element 22. At the same time, the lower shaft rod 35 rotates accordingly, and under the action of centrifugal force, the spring 36 is stretched, and the impact ball 37 impacts on the right side of the filter screen plate 21 and the left side of the filter element 22. During the impact process, the filter screen plate 21 and the filter element 22 shake off the dust on the surface.

[0036] The impact ball 37 is made of solid metal material, and a rubber layer is wrapped on the outer surface of the impact ball 37.

[0037] By using the impact ball 37 made of solid metal material, the impact effect can be improved, and by the rubber layer wrapped on the surface of the impact ball 37, the wear on the filter screen plate 21 and the filter element 22 can be reduced.

[0038] Working principle: The ventilator sucks in the dust from the outside through the left side of the box body 1, and then intercepts large-particle dust or sundries through the filter screen plate 21, and then intercepts small-particle dust through the filter element 22 to achieve the purpose of ventilation and dust removal. When it is necessary to clean the filter screen plate 21 and the filter element 22, the ventilator stops running, and then the shielding plate 13 is pulled out from the strip hole 12. By energizing the double-shaft servo motor 31 to rotate forward or backward, when the lead screw 33 rotates forward, under the action of the nut 34, the brush plate 32 descends, and vice versa, so that the brush plate 32 during the lifting process cleans the left side surfaces of the filter screen plate 21 and the filter element 22. At the same time, the rotating impact ball 37 impacts on the filter screen plate 21 and the filter element 22 under the action of centrifugal force, and then under the action of inertia force, the dust on the filter screen plate 21 and the filter element 22 is shaken off. Thus, under the wiping and impact actions, the cleaning effect of the filter screen plate 21 and the filter element 22 is improved. The cleaned dust falls into the drawer 42 to complete the centralized collection of dust.
